When your car's Check Engine light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.
If you experience any bleeding period after this 20 days, it will probably be the real period. This normally comes at about 4 to 6 weeks after the miscarriage.
When to Expect Your Period. By far, when you can expect your period to return is probably the most common question women have about physical recovery after a miscarriage, and the answer varies depending on the person. The gestation at the time of the loss often affects the timing of when you will resume menstruation. Generally, depending on how far along you were in your pregnancy when you miscarried, you should get your first period after a miscarriage in one to three months. If you were further along, it might take longer for your period to come back than if you were in early pregnancy when the loss happened.
